Lizette,
There is an option within CA 1 called SMS that can be set to EXT (EXTended).
This will store the SMS Management class in the TMC record at the
file-level.
For Dataclas you would have to use the new (new with 14.0) TMOKEYxx member
and have the Dataclas stored at the volume level in the
Yes,
Data class is used for choosing tape parameters (MEDIAn, encryption, etc).

That shows the storage group but not the dataclass.
I’m pretty sure DATACLAS, for both disk and tape, is used during ACS

We’re part-way through a migration from an antique TS35000 to a DLm.

Well, that's weird indeed. CBR1180I does not appear to be a variable-content
message. Maybe because you're on a DLM. It is a DLM, right?

Yep, data class is stored in the VVDS, plain as day, right between the storage
class and the management class for each dataset that has one. If it doesn't
have one, there are three bytes of X'00' between the storage class and length
of the management class.

Are you sure? I see LM DC: on my display; that's the construct where size is
defined in the Library Manager. Dataclass is definitely stored (I'd guess in
the VVDS, not sure honestly, but certainly in the LM for tape volumes); check
your dataset records in a DCOLLECT run . . . .

I’m pretty sure DATACLAS, for both disk and tape, is used during ACS routines
and allocation in general, but isn’t
Tape dataclass is on the volume level. You can use 'd sms,vol(vv)'.

Lizette, I listed some volumes via CA-1, ISMF and LISTCAT and so far I cannot
see the dataclas in the display.
I'll poke around some more

I am a little foggy on this
Is there a way with CA-1 or ISMF to determine what Dataclas a tape dataset
used?
I have various sizes of tape in my TS7700. I am trying to see what dataclas
was used for a specific dataset
Thank you
Lizette
